Sintx Technologies, Inc. (NASDAQ: SINT) is a medical materials company specializing in the development and manufacture of silicon nitride-based biomaterials for surgical and implantable medical devices. Its proprietary silicon nitride ceramic combines mechanical strength, biocompatibility and intrinsic antimicrobial properties, positioning it as an alternative to traditional metal and polymer implant materials. Sintx’s primary focus is on applications in spinal fusion, trauma fixation and dental implantology, where device performance and long-term biological response are critical.
The company’s core product offerings include silicon nitride powders for advanced implant fabrication and finished implantable components designed for interbody spinal fusion cages, spinal fixation hardware and trauma plates and screws. Sintx employs proprietary ceramic processing and additive manufacturing techniques to produce high-purity, high-density silicon nitride parts. This advanced material has demonstrated reduced bacterial adhesion, enhanced osteointegration and favorable imaging characteristics under X-ray and CT scanning compared with conventional metallic implants.
Founded in 2006 and headquartered in Salt Lake City, Utah, Sintx Technologies operates research and manufacturing facilities in the United States. The company has built a portfolio of patents covering silicon nitride composition, processing methods and medical device designs, and it collaborates with implant manufacturers, contract research organizations and academic institutions to advance clinical evaluation and regulatory approvals worldwide. Through distribution partnerships and OEM agreements, Sintx serves both domestic and select international markets, supporting early adopters in the spine and trauma segments as well as emerging applications in dental and orthobiologics.
Sintx is led by an executive team with experience in biomaterials, medical device development and regulatory affairs. The company continues to invest in R&D to expand its silicon nitride platform technology, pursuing new indications and commercial alliances that leverage the unique combination of strength, bioactivity and antimicrobial performance inherent in its ceramics.
